  • First Impressions: Sigma SD1

    Get your Foveon!

    • By Philip Ryan on May 24, 2011

    While we're still waiting for a full production sample of Sigma's new flagship DSLR, the SD1, we did get to check out a preproduction unit recently. As with all preproduction samples, you never quite know what is final and what isn't. We're told that the design of the body is final, so buttons and the overall shape of the camera should remain the same. But, it's impossible to know anything about what might change inside the camera and it should be assumed that the firmware will go through at least one more iteration before everything is finalized.

  • Battle of the 85mm f/1.4 Lenses

    Fast, sharp and perfect for action, portraits, low light and more. The 85mm focal length is indeed great, but which 85mm f/1.4 is best?

    • By Peter Kolonia on March 14, 2011

    The high-speed 85mm—a photographer’s most versatile lens. In bright or hardly any light, it produces the highest-quality portrait, action, wildlife, wedding, product, and fashion images. In fact, at this writing, Nikon offers three different 85s, Canon two, and Sigma, Sony, and Zeiss, one each. The Pentax 55mm and Sigma 50mm f/1.4 lenses both become (near) 85mm on APS-C bodies. Each is made for pros and built to last. Spanning the price range from reasonable (the f/1.8s) to ridiculous (Canon’s f/1.2), there’s a fast 85mm out there for every photo budget—and ambition.

  • Lens Test: Sigma 50-500mm F/4.5-6.3 APO DG OS HSM

    Bigma has shed some weight and picked up optical image stablization.

    • By Julia Silber on July 13, 2010

    The first version of this lens earned the nickname Bigma for its 4.25-pound heft and huge size.Now comes Son of Bigma ($1,600, street), lighter at a little less than 4.2 pounds, yet with a number of optical improvements including image stabilization.Like the original, this 50–500mm boasts the broadest zoom range—10X—of any Sigma full-frame lens. That’s far more range than the Canon 100–400mm f/4.5–5.6 IS (4X) or Nikon 80–400mm f/4.5–5.6 VR (5X) stabilized full-framers.
